Please help! I have just transferred into a new uni and i have never done any programming before. i have been asked to complete an assignment which i assume is simple however seeing that i have never done any b4 i really dont understand what is going on here.. i will attach scans of the assignment.. any help would be greatly appreciated. Any at all!!

no one here is going to do your assignment for you. You will have to ask questions or make an attempt, and we will help with errors and problems you have.

No I wasn't hoping that someone would do it for me at all. Not what i had in mind trust me. I was simply hoping that someone could help me understand some of the terms used, maybe give push in a general direction so i can try start it. At the moment it feels as though i am looking at Chinese.

If someone you could maybe show me how to successfully create classes. or explain what the special object class.

that was a much better question!

Try the tutorials here: http://www.python.org/doc/Intros.html
They start basic and descriptive and move up into more complex things

Alrighty o! i had a look at your tutorial and have created the classes the way that are supposed to look. so what i need help with is how to add an attribute "displayinfo" which will display the details of my three objects.

#!/usr/bin/python


# your 3 Classes are: Publication, Book and Disc
# 1st Class is Publication with Special Class (object)





class Publication:
def __init__ (self,pubtitle,pubgenre):
self.title = pubtitle
self.genre = pubgenre
self.pubID = 'xxxx'
return



class Book(Publication):
def __init__ (self,pubtitle,pubgenre,bookpages):
Publication.__init__(self,pubtitle,pubgenre)
return






class Disc(Publication):
def __init__ (self,pubtitle,pubgenre,bookpages):
Publication.__init__(self,pubtitle,pubgenre)
return






def test():

book1=Book('Lord of the Kings','Science Fantasy',987)
book2=Book('Love Never Dies','Romance',176)
book3=Book('Ten to Midnight','Crime Thriller',235)

disc1=Disc('Hello Dolly','Comedy',115)
disc2=Disc('Lord of the Rings','Science Fantasy',542)
disc3=Disc('Needles and Pins','Medical Reference',120)

print '\nTesting...\n'

book1.displayInfo()
book2.displayInfo()
book3.displayInfo()

disc1.displayInfo()
disc2.displayInfo()
disc3.displayInfo()


if __name__=='__main__':
test()
print'\nHave a nice day'



results are!!!:

Testing...

Just so you know, it is imperative that you use the code tags in the forum when you're posting python code. The whitespace is quite needed. Anyway, your problem is in your Book class. It should appear like this, with the additional displayInfo() method.

Right now, you're trying to call a method that doesn't exist
